Dechlorination of 2,3,5,6-tetrachlorobiphenyl by a phototrophic enrichment culture
(Elsevier, 1992-07-15)
A phototrophic enrichment culture, using acetate as carbon source, reductively dechlorinated 2,3,5,6-tetrachlorobiphenyl. ortho chlorines were removed preferentially over meta chlorines. Tri- and dichlorobiphenyls were the ...
Comparison of the Host Ranges and Antigenicity of Cryptosporidium parvum and Cryptosporidium wrairi from Guinea Pigs
(Blackwell Publishing Ltd, 1992-05)
Oocysts of a Cryptosporidium isolate from guinea pigs were not infectious for adult mice, but were infectious for two of three newborn calves and for suckling mice. However, oocysts isolated from calves or mice infected ...
Gene expression of the insulin-like growth factors and their receptors in cultured human retinal pigment epithelial cells
(Elsevier, 1992-01)
Insulin-like growth factors I and II (IGF I and II) are polypeptides with both growth-promoting and insulin-like metabolic effects16,27. Immunoreactive IGF I is present in the retina14 and both IGF I and II are present in ...
An intramolecular, Schmidt reaction of an alkyl azide with a carbocation. The generation and rearrangement of a conformationally restricted secondary aminodiazonium ion.
(Elsevier, 1992-09-08)
Treatment of azidoalkene 2 with triflic acid produced the bridged bicyclic enamine 3 by an intramolecular Schmidt reaction. Rearrangement of the intermediate aminodiazonium ion 5 is completely regioselective.
Transferrin: A potential source of iron for oxygen free radical-mediated endothelial cell injury
(Elsevier, 1992-04)
The ability of transferrin to potentiate oxygen free radical-mediated endothelial cell injury was assessed. 51Cr-labeled endothelial cells derived from rat pulmonary arteries (RPAECs) were incubated with hydrogen peroxide ...
Refined localization of human connexin32 gene locus, GJB1, to Xq13.1
(Elsevier, 1992-06)
Connexins are the peptide subunits of gap junctions that interconnect cells to allow the direct, intercellular transfer of small molecules. Recently, the human connexin32 gene (locus designation GJB1) has been regionally ...
Inactivation of Escherichia coli 2-amino-3-ketobutyrate CoA ligase by phenylglyoxal and identification of an active-site arginine peptide
(Elsevier, 1992-11-15)
Treatment of homogeneous preparations of 2-amino-3-ketobutyrate CoA ligase from Escherichia coli, a pyridoxal 5'-phosphate-dependent enzyme, with phenylglyoxal, 4-(oxyacetyl)phenoxyacetic acid, 2,3-butanedione, or ...
Population balance between producing and nonproducing hybridoma clones is very sensitive to serum level, state of inoculum, and medium composition
(Wiley Subscription Services, Inc., A Wiley Company, 1992-02-05)
Secreting and nonsecreting hybridoma populations derived from the murine hybridoma cell line 167.4G5.3 were each grown in batch culture in low serum and serum-free media. Under serum-free conditions, a secreting population ...
Localization of the gene encoding R[kappa]B (NFRKB), a tissue-specific DNA binding protein, to chromosome 11q24-q25
(Elsevier, 1992-10)
Although NF (nuclear factor)-[kappa]B binds in vitro to several of the [kappa]B regulatory elements found in cellular and viral genes, another DNA binding protein, R[kappa]B, also binds to a related variant of the [kappa]B ...
Gene expression of the insulin-like growth factors and their receptors in human neuroblastoma cell lines
(Elsevier, 1992-10)
Insulin-like growth factors (IGF) I and II are polypeptides with both growth-promoting and insulin-like metabolic effects. The developmentally specific expression of IGF I and II in the nervous system implies a role for ...
